To all whom it may concern:

Beit lmown that I, KAR'L- HELM IJUDWIG SECK, subject of ills German Emperor, residing at 22 Augusta Anlage, Mannheim, in the German Empire, vented certain new end useful Improvements in Driving Mechanism for Motonfiriven Cultivators, of which the feilosving is a specification.

This invention releies to driving mechanism for motor-driven egriouitursi .eultivstors or she like of the :hype which the driving wheels are s-heft through 'difierential and cliwngespeed eering, the eonntershefts being adopted to coupled oogether so as to note-he in unison when nequired, such as when one of the wheelsskids upon she ground, the object thereof being so transmit the whole of ihe power to the other wheel.

The :objed; of the presene in-veniion is $0 simplify cost of the driving purpose mechanism :is providsd fior preventing the coupling of like driving Wheels when the lowest or one of the lower speeds (ii-the change speed gearing is in gear and for preventing the said speed or speeds from being put into gear when the wheels are coupled.

- n order that the invention may he more clearly underssoood, reference is made to the eocompsnving drawings wlrereon one- W invention is shown by Way of example. v
